Abstract X-ray diffraction and magnetic-susceptibility measurements have been carried out for single phase KxC70 (x=1, 3, 4, 6 and 9) compounds synthesized by heating stoichiometric amount of K9C70 and C70. The x-ray diffraction profiles show no structural transition down to 10K. The fairly large temperature-independent paramagnetic contribution was observed in x=3 and 4. The electrical resistivity has been measured for K evaporated C70 film with increasing K thickness. Two resistivity minima were observed at x=1 and 4. |
